...Photogenic manipulation, containing the theory and plain instructions in the art of photography edit

"A new edition" suggests that there had been earlier editions and that the earlier text was not Bingham's. Further editions appeared: with Bingham's text? Can this be improved?--Wetman (talk) 14:52, 8 September 2014 (UTC)Reply

Your interpretation is correct, the first three editions were by someone else, the fourth edition by Bingham was completely rewritten though (and further rewritten and expanded by Bingham in later editions). No idea how to better present this, I'll think about it. Thank you for your other edits to the article.Fram (talk) 15:00, 8 September 2014 (UTC)Reply
